COLLAPSIBLE ROPE $POOL.

Application filed October 13, 1923. Serial No. 668,343.

T 0 all whom it may concern:

Be it known that we, GILBERT G; DAVIS amlMA'rrr-rmv J. DAVIS, bothsubjects of the King of Great Britain, and both residents of the city ofVancouver, in the Province of British Columbia, Canada, have inventedcertain new and useful Improvements in Collapsible Rope Spools, of whichthe following is a specification.

Our invention relates to improvements in collapsible rope spools, theobjects of which are to provide means whereon a rope or cable can beconveniently wound, and after such winding, the coil may be easilyremoved therefrom, a further object is to provide such a device as maybe connected to the overhanging end of a driven shaft and entirelycarried thereby so as to be adaptable for use on and as an auxiliary toexisting winding machines such as donkey engines and the like. .Theinvention consists essentially of a drum freely rotatable upon a drivenshaft and having a plurality of slats supported beyond the periphery ofthe drum andupon which the rope is wound, and. means whereby the slatsare withdrawn radially inward that the coil of rope may be removedtherefrom, as will be more fully described in the followingspecification in which F lg. 1 is a general sectional view of ourinvention.

Fig. 2 is an endview showing the manner of locking the spool in windingposition.

In the drawings like characters of reference indicate correspondingparts in each figure.

The numeral 1 indicates a driven shaft upon the end of which the spoolis supported. 2 is a drum having peripheral walls 3 and an end wall 1-,centrally of the drum 2 is a recess forming a bearing 5 into which theshaft 1 is fitted for rotation and also as a support for the spool. 6 isan annular recess in the end wall 4 and surrounding the bearing 5. 7 isa collar suitably fastened to the shaft and rotatable within the recess6 for the purpose of holding the drum in position longitudinally of theshaft 1. The numeral8 indicates a flange bolted to the end wall 4and-covering the collar 7, the outer face of the flange is provided withclutch teeth 9, which are adapted to be engaged by the correspondingclutch teeth 10 clutch teeth 10 and 9 tothe drum 2.

The numeral 17 indicates a shaft extend ing outwards from the base ofthe bearing 5 of the drum 2 upon which is mounted a freely rotatablesleeve 18 havingan external thread 19 thereon, the outer end of thesleeve being secured to a boss 20 having a central recess 21 and a pairof upstanding lugs 22 upon its outer end. Secured to one side of theboss 20 and projecting beyond the end thereof is a spring catch 23. Thesleeve 18 and its boss 20 is held in position by a nut 24: and acastellated locknut 25 screwed upon the outer end of the shaft 17, thelocknut when in fixed position projecting the depth of itscastellat-ions beyond the face of the boss 20* adjacent the spring catch23.

The numeral 26 indicates a handle upon a forked crank 27 which is hingedto the lugs 22 by the pins 28. 29 is a tongue extending inwardly betweenthe forked members of the crank for the purpose of engaging thecastellated nut 25 when the handle is folded, as shown, to lock thesleeve 18 against rotation upon its shaft. 30 is an aperture in thecrank through which the free end of the spring catch 23 extends toform areleasable grip to the crank.

The numeral 31indicates a boss having an internal thread 32 inengagement with the thread 19 of the sleeve 18. 33 is a plurality ofspokes extending radially and tangentially from the boss 20, the outerends of each of which are apertured to receive a pin 34. Upon theperiphery of the drum 2 are pairs of brackets 35 .in whichare slots 36sloping towards the axis of the drum and at the outer end of the drumare corresponding pairs of brackets 37 having a pivot pin 38, thepurpose of which will hereinafter appear.

The numeral 89 indicates generally, a plurality of slats each having alongitudinal member 40, a right angular member 41 at one end and a fork42 at the opposite end which fork is provided with a pivot pin adjacentits outer extremity. 44 are rocking arms each having an outer projectingmember 45 and a cranked member 46, the member 44 is pivotally connectedadjacent its longitudinal centre within the fork 42 by the pin 43 eachof the arms 44 being fulcrumed upon the pin 38 between a pair ofbrackets 37.

The numeral 47 indicates a plurality of links each of which arepivotally connected at opposite ends to a spoke 33 by the pin 34 and tothe cranked end 46 of the rocking member 44 by a pin 48.

Having thus described the several parts of our invention we will nowbriefly explain its use.

When it is desired to wind up a coil of: rope the collar 11 is moved bymeans of the lever 15 to establish a driving connection with the drum 2by means of the clutch teeth 9 and 10, the rope is loosely attached to aright angular member 41 of one of the slats 39 so that on the rotationof the drum the rope is coiled upon the slats, the ends of the coilbeing held in position by the member 41 of the slats 39 and the outerprojecting members of the rocking arms 44, the clutch collar iswithdrawn when the rope is fully wound and the drum brought to rest, thecoil being subsequently bound against unwinding in any suitable manner,the crank 27 is then swung over into the position shown in dotted linein Fig. 1, and the sleeve 18 rotated by the handle 26 cansing the boss31 and its spokes 33 to move lengthwise of the shaft 17 towards the drum2 thus bringing the rocking arms 44 to a position substantially parallelwith the drive shaft 1 and simultaneously drawing the slats 39longitudinally outwards of the drum and disposing their longitudinalmembers 40 at a tangent to the walls 3 of the drum 2 so that the coilmay be entirely freed from, binding connection therewith and bodilywithdrawn.

After the coil has been withdrawn, a reversal of the rotation of thecrank 27 restores the slats in position for further coil winding, andthe folding over of the crank causes the tongue 29 to engage acastellation of the lock nut 25 thus locking the slats and rocking armsin winding position.

lVha-t we claim as our invention is:

1. A rope spool comprising a drive shaft, a drum upon the shaft,longitudinal slats carried by the drum each having a right angularmember at one end and a pivotally connected member at the opposite endbetweenwhich a rope is adapted to be coiled, a threaded sleeve rotatableupon an axial shaft and means carried by the sleeve for moving thepivotally connected members into and out of parallelism with the driveshaft.

2. A rope spool comprising a drive shaft, a drum upon the shaft,longitudinal slats carried by the drum, each having a right angularmember at one end and a pivotally connected member at the opposite endbetween which a rope is adapted to be coiled, a threaded sleeverotatable upon an axial shaft, means carried by the sleeve for movingthe pivotally connected members into and out of parallelism with thedrive shaft, and means for locking the threaded sleeve upon its shaft.

3. The combination of a drum provided with a tubular bearing annularlyrecessed at one end. a shaft extending into said bearing, a collar fixedto the shaft and positioned in the recessed portion of the bearing and aplate secured to the drum and covering the aforesaid recessed portion ofthe bearing to retain the collar therein.

4. The combination with the structure recited in claim 3 of means forclutching the shaft to the drum comprising clutch teeth carried by theaforesaid plate, a clutch member slidably keyed to said shaft andprovided with clutch teeth for said engagement with the teeth of saidplate.

5. A rope spool comprising a drum, a plurality of brackets arranged inpairs around the surface of the drum adjacent one end thereof, aplurality of slats spaced around the drum with one end of 'each slatarranged between the brackets of one of said pairs and pivotally andslidably secured thereto, fixed guard projections carried by theaforesaid ends of the slats, movable guard projections pivotedintern'icdiately to the remaining ends of the slats and to portions ofsaid drum and means connected to the movable guard projections operableto shift said projections to a position in line with said slats from aposition at an angle thereto.
